hello fellow camaro enthusiasts i am new to third-gen forums. okay i have an LT1 350 5.7L it was originally TBI but changed it over to carburated so i don't have to deal with the wiring and ecu controlled components. I plan on putting it into a 90 camaro Rs, but my question is.... what wiring would i still need from the stock 3.1L mpi engine? also if anyone has any experience with rocker arms what is the torque specs for the LT1?... I've been searching every website and it says 8.3 ft/pounds for the rocker arm cover bolts, but my torque wrench doesn't go that low, is there anyway to tell whether they are too torqued? I am 17 if that explains why I'm asking many questions. please get back to me as soon as possible.

 

So you will be running a regular SBC mech/ vac advance dist
( Like a HEI ) , mounted in the intake; no LT1 spark electronics ?
With a reg dist ,all you need is a 12V supply when the key is on to the dist ;which would have come of the 3.1 dist ( usually a thick pink wire )
The white next to it gets hooked up to run the tacho

 

thanks i will look for that thick wire. and yes im going to be running a HEI vacuum advanced distributor in the intake. i siliconed the optispark dis cuz its useless.but also i am still wanting to run the electric fan and the alternator.

 

The entire pass side wiring harness can be removed - that's all ECM related wiring that won't apply to a carbed swap.

 

I recently swapped out my 2.8 card v6 and im ready to drop in a fresh 383 stroker carburated. Can anyone let me know what im all going to be needing for wiring? I am running a HEI Distributor with vacuum advanced and im pretty sure ill be fine with the wiring for that but i dont know what im getting into with the alternator or any sensors.

Ive searched TGO alot for stickys on this but no one really posted anything on a v6 carb to a v8 carb swap...

Thanks alot

 

You put your carb on, swap the sensors ( for gauges ) to the new engine and remove any wiring ( to do with original injection ) that doesn't have a home .Alt wiring stays as is
Will need some means of operating fuel pump and fans if the ECM is gone

 

I am using a mechanical fuel pump...what is a ECM?

 

Electronic Control Module. The computer the runs the fuel injection. With a carb, it is dead weight.

Your mechanical pump might not like pulling fuel through the stock in tank pump, and filter though.......

 

Is my car even going to have an ECM being that its a carbed v6?
&
What would i have to do to get my mechanical pump working thru the intank pump then tho? That whole issue passed right by my, thanks alot for bringing it to my attention

 

If this is the '82, then you wouldn't have a in-tank fuel pump on it since it was carbed originally - so no need for any regulator or worrying about the in-tank pump.
